 File format and architecture are automatically detected.
 
-### Help with iOS support
+For Apple Universal Binaries, multiple output files will be generated, with each filename suffixed by the index of the image in the Universal Binary. Unsupported images will be skipped.
 
-Mach-O (iOS) file format is not currently supported. Please contact me via the contact form at http://www.djkaty.com if you have a rooted iOS device and can produce cracked IPA files.
+### 64-bit binaries
+
+Il2CppInspector does not currently support 64-bit IL2CPP binaries. 64-bit Mach-O files will be parsed without crashing but there is currently no support for 64-bit CPU architectures so automatic inspection will fail.
+
+### Problems
+
+If you have files that don't work or are in an unsupported format, please open a new issue on GitHub and attach a sample with details on the file format, and I'll try to add support.
